I've taken two workshops from Marsha McCloskey. One of them was five days and the other was two days. She taught us how to draft our blocks. I loved her instruction. She is my favorite teacher.
She is all about precision piecing, not paper piecing. She did mention that others use paper piecing, but not her.
Attached are pictures of the quilts that I did from her workshops. The first one was before I had finished my first quilt.
